SASH-STILE PLOWING A N DB Q RIING MACHINE.

SPECIFICATION forming part of Letters Patent No. 725,461, dated April 14, 1903. lApplication filed September 13, 1902.: ,Serial as. 123,296. (No model.)

To all whom it, may concermr I Be it known that I, ANDREW A; LOETSOHER, a citizen of the United States, and a resident of Dubuque, in the county of Dubuque and State of Iowa, have invented a new and'lmproved Sash-Stile Plowing and Boring Machine, of which the following is a full, clear, and exact description. i l

My invention relates to mechanism for plow-,

ing and boring the stiles used in windowsashes to attach the'acords or chains to the same for hanging the weights thereto.

I I willdescribe a sash-stile plowing and bor- I ing machine embodying my invention and then point out thenovel features in the appended claims.

. Reference is to be hadto the accompanying drawings, forminga part of this specification,

in which similar chara'cters'of reference indicate correspondingparts in all the figures.

sake of clearness. of one of the stiles. Fig. 6 is a plan of the same. Fig. 7 is a horizontal section upon the line 7 7 of Fig. 3 looking in the direction of r the arrow. Fig. 8 is a side elevationof one of the so-called thick cutters.

Fig. 10 is a section'upon the line 10 10 of Fig. 8. Fig. 11 is a front elevation of one of the plan showing a pail-of stiles arranged to be operated upon simultaneously. 1

A frame 1 is provided with brackets 2, upon which is mounted a table 3,-inclined, as's hown in the drawings. The frame isjalso provided with bearings 4,5, 8, and 9,supporltin'g the guard-plate 12, secured upon a plate 13, these vpin 17 "jectingarms 17, which engage a rodj17l and Fig. 3 isv Fig. 5 is a side elevation I Fig. 9 is a' section of one of the so-called thin cutters.

catedmore particularly in Figs-2 and 3, by

means of screws 15. XThe guard-plate 12 is held in position upon the supporting-plate 13 by means of screws 16. I II A guide 17, having the general form of an temporarily in position by means of aspring- The clamp 17v is provided with proare caused to clamp the same bytmeans of a bolt l7 Upon the forward end-of the rod l7 -tis a'stop-plate 17 When it is desired to adjust this stop-plate, the bolt l7 iis loosened and the rod 17. slid backward or forward, the bolt 17? being then tightenedwith a wrench or a hand-wheel attached thereto,as preferred. The guide 17 is furtherprovided'with slots 17 which are engaged by adj usting-bolts 17 and the guide is also provided with adjustment-holesl7 engaged by the pin 17". The

bolts 17 engage ablock 18,"slidably"1nounted L-beam, is provided with a clamp 17, secured I upon a track 19. .By loosening the bolts 17 the guide 17 maybe movedinfa lateral direction relatively to the block 1 8, and therefore may be adjusted laterally. The'track 19 is provided with bevel surfaces 20 21, which are engaged bythe block 18.1, i e

A pitmanz22 .is connected by a= pivot18 with the slide-block. 18 and isalsoconnected- I with the upper end of a lever 23. Theilower end of the lever 23 is provided with an enlarged head 23 which is rigidly secured to a lever 24, so that when the lever-24 is rocked the pitman 22 causes thenblock'l S, carrying 'the'guide 17, to slide along the track 19.

-The levers 23 and :24 arev mounted upon a shaft 25, butnot keyed thereto; Mounted in bearings 27 is a revolubleshaft 2,8,provided with fixed and loose-pulleys 29 30. Upon this shaft are keyed pulleys .3132, and upon these" pulleys are mounted, the respective belts 33 34, connectedwith'the driven pulleys 35jand 36 for the purpose of actuating the revoluble cutters.

Mounted loosely large sprocket-wheel 37, provided vwith'a bearing-roller 38 and acam 7 7, keyed to thehub upon the shaft 28 i s a v49 with another step cone-pulley 50.

of the pulley. The sprocket-wheel carries a sprocket-chain 39, which is connected with a smallsprocket-wheel 40, running loosely upon a shaft 41. The small sprocket-wheel 4.0 is provided with one member 42 of an ordinary clutch, the other member 43 of the clutch being movable relatively thereto in the usual manner.

The clutch member 43 is carried upon a lever 44, this lever being connected with a treadle-lever 45, the treadle-lever being pivoted at 45 and provided with a foot-plate 46, whereby the same is actuated. A weight 47 normally holds the clutch members in engagement with each other, so that movement of the sprocket-chain normally causes the sprocket-wheel L0 to rotate with the revoluble Sllftfhfll.

By placing the foot upon the foot-plate 46 the clutch members are disengaged, and the rotation of the sprocket-wheel 40 is thereby stopped. The purpose of the treadle is to throw the feed mechanism into and out of action, so that the feed of the stiles toward the cutters may be controlled at will. It the clutch members are in engagement, so that motion is communicated by the chain 39 to the sprocket-wheel 37, the roller 38 is caused to make periodical contact with the lever 24;, thereby causing the lever 23 and pitman 22 to draw the guide 17 and stop-plate 17 toward the revoluble cutters. The feed of the stiles toward the cutters is therefore automatic except in the sense that the feed mechanism may be rendered operative or inoperative at will.

A step cone-pulley 48 is keyed upon the shaft 28 and is connected by means of a belt y shifting the belts upon these cone-pulleys the speed of the shaft 41 may be changed relatively to the speed of the shaft 28. A pulley 51 is keyed upon the shaft 28, and from this pulley a belt 52 connects with a revoluble drum 53. This drum is mounted upon a vertical shaft 54:, disposed parallel withanother vertical shaft 55, these two shafts being geared together by means of cog-wheels 56 and 57. The shafts are disposed in vertical bearings 58, 59, 60, and 61 and are provided with angers (52 63, which pass upward through holes Cal in the table or rest 3.

The bearings 58 59 60 6 l, carrying the augershafts and angers, are mounted upon a block (50', which is slid-ably mounted between the members 67 of a slideway. \Vhen the block 66 moves upward, it thrusts the angers through the holes 64 (55, and when the block moves downward the angers are withdrawn from these holes. I i

The slideway (i7 is secured upon a track 68. Through a slot 69 in the track projects a beam 70, rigidly connected with the sliding block 66. The beam 70 is adjustably connected by means of bolts 72 with a trip-rod 71, as shown more particularly in Fig. 4. a

[ The lower end of the trip-rod 71 rests upon a lever 73, provided witha set-screw 7 4.,whereby the trip-rod is secured rigidly upon the shaft 25. Another lever 75, provided in like manner with a set-screw 76, is secured upon the shaft 25 and engages the cam 77, which is mounted rigidly upon the hub of the sprocket- Wheel 37 and is revoluble therewith; Each thereby raising the rod, and with it the auger through the holes Get 65.

The stiles are shown at A B. Each stile is bored by one of the'augers, the hole 78 thus tion of the stile, as indicated in Fig. 5. The socalled narrow slot is shown at 79 and connectsthe hole 78 with the so-called wide slot 80, as indicated more particularly in Figs. 5 and 6.

The angers rotate in opposite directions for the purpose of preventing displacement of the stiles-that is'to say, any tendency which one auger might have to twist the stile relatively to the rest or board is corrected by a contrary tendency of. the other auger to twist another stile in the opposite direction. By this arrangement I am enabled to work upon two stiles at a time. I place the two stiles upon the rest or table 3 and, if necessary, adjust the position of the stop-plate l7 into such a position as will correspond with the length of the stile.

The revolution of the large sprocket-wheel 37 causes the cam 77 to trip the lever 75, and thereby thrust the augnrs upwardly, and the augurs being always in motion by means of the belt 52, as above described,the holes are bored instantly. As soon as the holes are bored or when the angnrs are at their maximum height the lever will leave the cam 77,and thesliding block G6,holding the angers, will drop back instantly to itsnormal position, and the roller 38 coming next in. conto draw the feed mechanism toward the revoluble cutters, as above described. The result is that the stiles are forced upon the cutters, the narrow and wide slots being cut at the same time. laid upon the rest at the wrong moment or if for any cause it is desired to stop the feed of the stiles toward the cutters, the workmen accomplish this purpose by means of the treadle, as above described. l

I think that my arrangementfor operating two stiles at the same time and for causing with this end in view, together with my arrangement of the thick and thin cutters in plain alinement With-the angers, is a very desirable one, which can be best appreciated by persons acquainted with the difficulty of sticker or separate machine. My feed mechtime the sprocket-wheel 37 makes a IGVOIU. tion the cam 77 trips the levers 75 and 73,

mechanism, so that the augurs are thrust made forming an angle with the general directact with the lever 24 .will cause the lever 23 If by accident the stiles are the angers to revolve in opposite directions doing this Work singly by attachment to a anism isalso very desirable-in fact, almost indispensable after a trialon that class of work.

I preferably place my machine alongside of the mortising-machine, so that the operator, who is usually a boy, intaking the stiles away from the mortiser 'can'do'both the plowing and boring at the same time and without extra cost or help. In other words,
